By applying Sutherland potential to this model, the new attractive term above is derived. 该模型应用到Sutherland势函数中,得到上面的吸引项;
The analytical radial distribution function ( RDF) of Sutherland potential ( SP) has been derived from PY integral equation by linear expansion of exponential term. 通过求解PY积分方程,得到了Sutherland位能模型径向分布函数式。
